Wow that sucks!

I moved to mailgun yesterday. I run an alert system for Google Analytics, so I can't afford delays of more than a minute, and even then...

So far so good with mailgun!

Thanks for the info on Sparkpost, definitely not tempted to move there ;)

Regardless of which sender you use, you must remember that email often appears "instant", but it really really isn't.

If you absolutely need to send notifications to users with "zero delay" then email is not for you, and SMS is probably not sufficient either.

No and honestly after using mailgun for about 3 hours now, I will not go back to sparkpost. I will be requesting a full refund since service was never rendered and if that is not answered, I guess chargeback.
